concern:

GILBERT It. COLEMAN, States, and a resident City, in the county of Hudson and have invented certain new and useful Improvements for the Applicationof Babbitt and Lining Metals to the Surface of Railroad and Other Journal Bearings, of which the cation.

following is a specifi- My invention relates to new and useful improvements in devices for the application of Babbitt and lining of railroad and other journal bearings. object isto provide such a device which will operate more efficiently,

and more even lining be lined. Heretofore metals to the surface Its provide a better and at the same time at which the bearings can mandrels have been used in connection with the lining of bearings buthave been used with separate and independent side pieces hammered into place. s1de pieces are coactin,

which have had to be In my invention the place'by operationof thesame means, maintaining substantial parallelism with one another throughout.

I have also provided my device with a series of mandrels mounted on a revoluble table so that the operator can apply the lining on one mandrel, turn the table, repeat the operation on the successive mandrels and by the time the original mandrel is. returned to been sufiieiently solid him the lining .will have w to allow for the removal of the bearing.

I have also provided each of the mandrels with a simple working clamp can be quickly moved at the proper time. tion in the drawings and description V2Ll1011S so that the journal bearing held in; place and easily re- I show in addidetails of my preferred construction. In so describing my preferred form, I do not,

however, limit myself to such construction,

the scopeof my. invention being pointed out in the claims.

' I Referring to thedrawings, I

Fig. l is a side elevation of my apparatus;

and

Fig. 2 is a plan view of same.

' The preferred form of my with a stand 1 on which is mounted provided apparatus is a ball thrust bearing 2 carrying table 3 free to rotate on the stand 1.- The table 31 carries ngs into which man- 'contact with the surface and are forced into ing 20. A look each other. description drels P, at", l and 4 are fitted. The mandrel 4 is made of an air cooled hollow construction so as to permit the free passage of air from the bottom to the top and carries internally cast fins 5 in order to give a great and assistsin the cooling. The side pieces may be fluted if desired. The side pieces are held in contact with the face of the mandrel by means of bar 8. Bar 8 extends through elongated holes 9 (shown in dotted lines in Fig. 2) in the sides of the mandrel. The bar 8 carries a stud 10. The stud 1O bears on the side pieces 6. A coil spring 11 and a nut 12 hold the side pieces 6 through the stud in v of the mandrel. A housing 13 protects stud, nut and spring from being fouled with molten metal. The bar 8 has a lateral movement on account of the elongated holes 9 It is actuated laterally by means of a screw 1 operating in the hole movement of the hand wheel 15 operating the screw 14, lateral movement is imparted to sides pieces6. The position of the side pieces regulates the thickness ofthe Babbitt or other metal imparted to the journal bearnut 16 prevents lateral movement of screw ltwith respect to the mandrel 4. The side pieces bear on the mandrels at their end portions only, namely,

at 7. and 7. Inaddition to affording an air cooling space, this construction forces the side pieces to stay substantially parallel to the vertical face of the mandrel 1 and to It will be seen from the above that by means of hand wheel 15 a quick regulation of the thickness of lining to be applied is afforded.

The journal bearing 20 to be lined is placedin the usual position against the mandrel and is held in place by means of clamp 21. Clamp 21 on its bottom side is provided with a rack 22. A gear 23 engages with this rack and is carried on the shaft 24. A part of the clamp 21, its underside rack and the gear 23 are carried in a housing 25. In Fig.

1 this housing is bro-ken away to show the poured in and the table 3 given a easily. taken out and another construction of elements 21 to 24 inclusive. To the shaft 24 is fixed a weighted handle 26. A. movement of handle 26 in the direction of the arrow shown in Fig. 1 rotates the shaft 24: and gear 23 and causes clamp 21 through engagement of the rack to be forced forward and hold the journal bearing in place; Adjustment of the clamp-21 can be made by adjusting the mesh of the rack .22 to the gear 23. In order to provide accessibility the housing "25 is provided with a detachablercover 2-7. The Weighted handle 26 when the clamp is in position maintains pressure on the railroad or other bearing to be linedand holds said bearing securely to side pieces 6. Thelining metal is applied in the space betweenthe journal bearing at 20 and the face of the mandrel. The pressure of thelin'ing metal when applied there isnot great enough to cause any movement of the journahbearings on account of the weighted handle. With the journal bearing20-in position and the clamp with the weighted handle 26 as shown, the Babbitt or lead lining is quarter turnto the left bythe operator. The lining operation is then successively repeated. hen the originalniandrel returns to the operator. the lining is suificiently solid to permit the removal of the bearing andanother bearing is inserted in its place and :clamped there as previously described. In

this way a continuous cycle of operation is provided.

As previously stated the table 3.is provided with a suitable number of openings to .cal'rysthe'mandrel. These openings havea lowerlip 30, shownin dotted'lines in Figs. 1 and 2, running around the lower part. The base 31 on each mandrel fits into the opening and is held by' means of the lip 30. The base' l of the mandrelwhen.inserted in the opening forms apart of thetable .3. After the mandrel hasbeen-placed'in position it isfixed by means of off setwasher 32 hearing on apart ofthe lip 30 and on.the base of the mandrel and is held by means of cap screw 33. The mandrel can therefore be one substituted for it. Mandrels of different sizes can thereis quite important that when the mandrel is in position the clamp 21 should bear on the central point of the'bearing which isbeing lined. hen different sized mandrels are lined I adjust the height. of the mandrel tobring the centralpoint of thelbearing oppositethe. clamp pieceby either increasing or decreasing the size of the metal pad 34 I have referred to the elampingmeans, as being brought to bear upon the central point of the bearing. This is usually proper but in the case of some bearings in which the weight and mass is not evenly distributed .by Letters Patent of the connecting said. mandrel bearings of the character space between said ends,

application of Babbitt or other lining to and in which the thickness of the metal can be regulated at will and at the same time such metal will be evenly distributed on.the surface ofthe bearing. The quick adjustment and clamping of the journal bearing and the easy regulation of the thickness of the'lining to be applied by means of'the hand wheel and side pieces and the continuous cycle of operation permits a much greater output and reaches a better result, because of the even distribution. of the lining on the surface of the'bearing. 'Mandrels of different sizes may be used interchangeably in my device.
